Description

This is the only A+ exam preparation guide that is mapped to several study resources. This new edition includes references to but is not limited to just the Cisco IT Essentials v4.1 course material to prepare for the new CompTIA 2009 A+ certification exams. Like all Cisco Press "31 Days..." exam prep books, it is organized by day, starting 31 days before the exam. Short, low-cost, and exceptionally readable, it gives students a highly-structured, simple tool that tells them exactly what to study each day to be fully prepared. 31 Days Before Your A+ Exams, Second Edition also contains easy-to-understand information on how to sign up for the exam, detailed explanations about what to expect during the exam, time-proven test taking strategies, and a tear out visual aid calendar. With these features, it is a true exam prep guide in every sense.
